"SDK Platform Tools component is missing!"

I am trying to add the add SDK Platform 1.6 to an existing Install of 2.2, with the help of this thread.

As suggested, I ran Help → Check for Updates which found and installed the following:

  + Android DDMS              8.0.1.v201012062107-82219
  + Android Development Tools 8.0.1.v201012062107-82219

It prompted for restarting Eclipse and when it restarted it gave me the following error message:

"SDK Platform Tools component is missing!
Please use the SDK Manager to install it."

Huh? Why? I still have the SDK Platform Tools on C:\android-sdk-windows that was working perfectly before I did this "upgrade".

What do I need to have both 2.2 and 1.6 supported in my development environment?

OK, here is what I did to fix the problem:

Open Eclipse. Then:
  Window > Android SDK and AVD Manager
   > Available Packages: 
     > Android Repository:
       + Android SDK Tools, revision 8
       + Android SDK Platform-tools, revision 1

[Install Selected]

The downloaded sdk software does not contain sdk platform tools.

For this, using cmd go to "C:\Program Files\Android\android-sdk\tools" directory and then type the following command to download those missing tools:

android.bat update sdk --no-ui

Then type y to accept all the licenses in cmd. Downloading will start in cmd itself.

Installing Android SDKs is done via the "Android SDK and AVD Manager"... there's a shortcut on Eclipse's "Window" menu, or you can run the .exe from the root of your existing Android SDK installation.

Yes I think installing the 2.3 SDK will fix your problem... you can install older SDKs at the same time. The important thing is that the structure of the SDK changed in 2.3 with some tools (such as ADB) moving from sdkroot\tools to sdkroot\platform-tools. Quite possibly the very latest ADT plugin isn't massively backwards-compatible re that change.

I don't understand why the files were relocated to /platform-tools from /tools. It seems ALL development tools I have tried, appcelerator for one, have their setup software look for these files in /tools and fail setup. The "work around" involves a few different bits of trickery wherein you either...1) set up a soft link to tell the operating system "if you look for file "x" here it is really over here. or 2) simpler method ... make a copy of all the /platform-tools default (pre-additional android sdk installations) files and place them into the /tools folder. this circumvents the relocation that the newer sdk have done. Then of course YOU MUST SET PATH ENVIRONMENT VARIABLES TO POINT TO THE SDK LOCATION (sometimes to the Android-sdk-[operating system name:Android-sdk-windows or Android-sdk-mac_x86 ect. ] and to the /platform-tools and sometimes to /tools. it is a trial and error pain. But when it finally is working ...it works.

Before update SDK components, check in Android SDK Manager → Tools → Options and set HTTP proxy and port if it is set in local LAN.
